Comparing resources with repository versions in Advanced mode
You compare repository files to view the differences between two versions of a file and to reconcile any conflicting changes. You can compare a repository file with the version of the file that immediately precedes it. For a local change and no outgoing change, you compare with the previous version in the repository workspace. For a local change and an outgoing change, you compare the local and the outgoing changes (previous version in the repository workspace). For an outgoing change but no local change, you compare the outgoing change with the previous version in the repository workspace (the last version before the check in).
